Abstract

In this paper, the combined method of finite element and multi-body dynamics is used to study the crankshaft assembly. The article first uses the finite element software to carry out the connecting rod the reliability of the connecting rod is proved by the state analysis. Then the regularity of crankshaft assembly motion is verified through the multi-body dynamics analysis of the crankshaft assembly rigid body, and finally, the law of the movement of the crankshaft assembly is discussed. The crankshaft assembly is coupled to the rigid flexible coupling analysis to study the load variation and dynamic characteristics of the key parts of the crankshaft assembly. Simulation analysis shows that: the connecting rod stress and deformation in the limit range, to verify the reliability of the connecting rod; the piston motion acceleration increases with the mixed gas deflagration pressure becomes larger, the variation of load of rigid bearing spindle neck in crankshaft main bearing the same; compared with the crankshaft assembly of rigid support, flexible support reduce the crankshaft load.
